Abstract: A thick and thin fibre has at least two axially-continuous grooves per filament with the entrance widths of the grooves lying between 0.2 and 4 mu m and the depths between 0.1 and 1.8 mu m. Such a fibre is made by dissolving out the easily-soluble polymer from a drawn composite fibre comprised of two thermoplastic polymer components having different solubilities. The fibre is of a silky nature and knitted and woven fabrics made therefrom have properties characteristic of silk fabrics.

Abstract: Disclosed is a bulky yarn made from a thermoplastic multifilament yarn. Each of the individual filaments forming the yarn has a randomly varying thermal shrinkage along its length. The filaments in the cross-section of the yarn also have randomly varying thermal shrinkages. The bulky yarn forms a plurality of loops having a stable and compact configuration, while the number of filament slack portions which project outwardly from the yarn surface is significantly decreased.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyester fiber capable of giving a woven or knit fabric having sufficiently high luxuriousness and high opacity and exhibiting new body feelings comprising unique feeling such as dry feeling, squeaking feeling and harshness in combination with mild luster. SOLUTION: This polyester fiber is composed of a mixture of a polyester containing >=1 wt.% of inorganic fine particles and a polyester having high dissolution rate in hot alkaline aqueous solution compared with the former polyester. The mixed polyester having high dissolution rate in the hot alkaline aqueous solution is linearly extended in the direction of fiber axis. The fiber forms micro-voids on the fiber surface and linear grooves in the direction of fiber axis by the thinning treatment with the hot alkaline aqueous solution and has a ΔLA value of
